We landed in Berlin this morning at 8 a.m. and, since we couldn’t check into our hotel until noon, went straight to our friends’ apartment in Mitte off Prenzlauer Allee. It’s in a traditional six-story stucco-style building with wide floor planks and beautiful plaster ceiling moldings. The place has six large rooms off a central hallway with ten-foot ceilings for a total of, we’d guess, about 1,200 square feet. The rent? 675 euros. We’d appreciate recommendations for neighborhoods for us to explore over the next couple of days. Ideas? GMAP
